Thanx for the link...but i'm working in plain win32 Api "NO MFC"...anyways thanx again for the help..if u find anything that has no MFC for displaying folders using SHELL in WIn32 please send me some reference..

MFC is nothing but a wrapper over the win32, so if you understand what that link is trying to say you can convert that logic into win32 calls in ur application.
but if you looking for spoon feeding anwers, then wait let me get my spoon.

How can I get this icon into an application?
Is there any way I can use SHGetFileInfo() without knowing a head of time the name of any document in particular?
Thanks

1.
The path to the file containing the HTML icon can be found in the default value of the foloowing registry key:
HKEY_CLASSES_ROOT\htmlfile\DefaultIcon
which usually "C:\Program Files\Internet Explorer\iexplore.exe,1", that is the first icon stored in the iexplore.exe. You can extract it from there.
2.
Take a screenshoot of windows explorer when it shows an HTML file, and add this bitmap to your project.
3.
Alternatively you can feed an CImageList with all the default icons, among others with the html default icon:
HIMAGELIST hSystemImageList;
SHFILEINFO ssfi;
hSystemImageList = (HIMAGELIST)SHGetFileInfo((LPCTSTR)_T("c:\\"),0,&ssfi,sizeof(SHFILEINFO),SHGFI_SYSICONINDEX | SHGFI_ICON);
m_ImageList.Attach(hSystemImageList);
pListCtrl->SetImageList(&m_ImageList,LVSIL_NORMAL);
And to find a path's index in the ImageList:
SHGetFileInfo((LPCTSTR)sPathToYourFile,0,&sfi,sizeof(SHFILEINFO),SHGFI_SYSICONINDEX | SHGFI_ICON );
pListCtrl->InsertItem(nInsertPos,sPathToYourFile,sfi.iIcon);
where sPathToYourFile should contain a valid path to an html file.

Hi!
I want to duplicate an object previously instanced:
<br />
CMyClass* pMyVar1=new CMyClass ();<br />
pMyVar1->Var="Value";<br />
CMyClass* pMyVar2=new CMyClass ();<br />
CopyMemory (pMyVar2, pMyVar1, sizeof(pMyVar1));<br />
This code doesn't work, because I think that the sizeof is not correct.
Is there a way to copy an object with all his values?
Thks in advance!

Something along the lines of
*pMyVar2 = *pMyVar1;
I just made a simple program that does the same thing and it works.
#include <iostream>
using namespace std;
class Class1
{
public:
int var1;
int var2;
};
int main()
{
Class1 * object1 = new Class1();
Class1 * object2 = new Class1();
object1->var1 = 1;
object1->var2 = 3;
object2->var1 = 2;
object2->var2 = 4;
cout << "Object1 Var1 = " << object1->var1 << endl;
cout << "Object1 Var2 = " << object1->var2 << endl;
cout << "Object2 Var1 = " << object2->var1 << endl;
cout << "Object2 Var2 = " << object2->var2 << endl << endl;
*object2 = *object1;
cout << "Object2 Var1 = " << object2->var1 << endl;
cout << "Object2 Var2 = " << object2->var2 << endl;
delete object1;
object1 = NULL;
delete object2;
object2 = NULL;
system( "pause" );
return 0;
}
object2 was switched in the output so I don't know why it wouldn't work for a more complicated class.

In theory what you did "could" work but in practice it is breaking so many rules that you should never do it.
In your case, "*pMyVar2 = *pMyVar1" should work, however, that assumes that if a default assignment operator isn't defined, that the default one (of just copying the elements blindly) would work. Many times it will not for an assortment of reasons. In those cases, you have to define your own assignment operator to handle the operation properly.
IMHO, the default assignment operator is more trouble than it is worth. Many people will thwart the default assignment operator if you shouldn't be performing that operation on the class. If your class can be used with an assignment operator, go to the trouble of defining one.

I'm going to patent thought. I have yet to see any prior art.

Very true, I hadn't thought of default = difficulties originally. If your class is just a bunch of int, double, etc the default = operator should work. But if you have char arrays, strings and other more complicated vars, definitely define your own = operator.

Thks!
I've defined my own = operator for my class and it works now.

Hi All,
I have two DLLs. One is an MFC extension dll that is using MFC serialization with CArchive. Another one is a COM component. I am using MFC DLL from COM DLL in order to initialize some data. Data is supposed to be serialized. However, MFC serialization fails in MFC code when it tries to find a runtime class object in a list of its runtime classes. It cannot find one and returns NULL which then throws an exception. When I use MFC DLLs from another MFC application to do exactly the same thing (serialize data on the same class), everything works perfectly fine.
Should I do something else when I use MFC DLL from COM component? Please note, COM component has been created to support MFC.
I will appreciate any help on this subject.
Thank you All.

Hi,
I'm working on a chat program that uses TClientSocket & TServerSocket.
With these I guess the only way to send 'loose' information is with Socket->SendText and for FileTransfer use Socket->SendStream...?!
Now I've made a protocol, something like:
-Client opens connection to server<br />
-Server Acknowledges<br />
-Client sends login-request (LOGIN, USERID, USERPASSWORD, USERIP)<br />
-Server returns if user == ... etc
...okay, what is the best option to send this? With a String, a Buffer or...?! And IS this a good way to do this at all?! 
And then what is the best way to 'read' the protocol...
With switch() or with if's... or a better way?
Thx a million in advance,
Jeroen(NL)

I have scanned msdn for a level 9.0 or 9.0b DirectX SDK that's available on CD and can't find it. The product is available as a 200+ MB download, but I would only do that if I were leaving for a two day holiday! Does anyone know where I can obtain a CD containg DirectX (for C++/MFC and Win32 development).
Many thanks for any help in this regard.

I have it on CD, it came with a book I got on DX 9.0 Rendering Engines. It's the DX 9.0a SDK I'm pretty sure. I've got the 8.1 SDK too if you like. If you'd trust me with an address I suppose I could mail you a burned CD of it. Wow, it'd actually be legal too since it's a free DL anyway! Just use the contact link on my website below to get in touch if you care to.

So I've got a DirectX Project that rotates some polys around. My problem is that I get compile errors saying PI is an undeclared indentifier. I've got the #include cmath statement ( BTW anyone know how to get the <> brackets to show up in code statements? ) and if I hover the cursor over a PI anywhere I get a tooltip "#define PI 3.14159...." Any idea what the problem is?

Not sure why your code won't compile. However, how about using this expression for defining pi?
const double PI = 4 * atan(1.0);

And to get the bracets show in these messages, use their HTML escape sequence codes. For > it is "& + gt;" and for < it is "& + lt;" (Remove the + sign, the quotes and write the entire sequence togeter in order to actual display it)

I just bought a PocketPC today, it is a HP iPAQ 2215 with
Windows Mobile 2003 OS and Intel PXA225 400MHz CPU.
Then I couldn't wait to download the SDK, then....
I downloaded the Microsoft Windows Mobile 2003 SDK from
Microsoft website, then it said in order to use VC++, I also
need to install eMbedded Visual C++ 4.0 and its service pack
before installing the SDK.
So I installed the eMbedded Visual C++ 4.0 and its service
pack 2, then I installed the SDK.
However after installing the Windows Mobile 2003 SDK, it only
contains the Pocket 2003 Emulator. The SDK itself is a console
application. It is prompting the SDK's tool directory. (it reminded
me the Java SDK) Isn't the Pocket PC 2003 SDK supossed to be
windows-based?
Then I opened the eMbedded Visual C++ 4.0, it looks exactly like
the Visual Studio 6.0 environment.
But I saw some people can use VS.Net environment to develop
the Pocket PC. There is also no new project type when I open
the Visual Studio .Net 2003.So I wonder if I have downloaded
the wrong tools? How can I use VS.Net to develop the Pocket PC?
Besides, on the SDK website, it said it can use C# and VB.Net
language. Why do I only get the Emulator and the console
prompt?

You have the right bits.
If you want to develop in C++ for Pocket PC 2003, you must use eMbedded Visual C++ 4.0 SP2. The SDK contains a great deal more than what you describe; the documentation and samples are installed to C:\Program Files\Windows CE Tools\wce420\POCKET PC 2003 (IIRC, don't have it installed here). eVC 4.0 looks exactly like Visual C++ 6.0 because it basically is - it's just been adapted a bit to support device development.
If you want to develop in VB.NET or C#, you need Visual Studio .NET 2003, and you must install the Smart Device Extensions from the VS.NET 2003 CDs. At present you cannot use VS.NET to write Pocket PC applications in C++ (feature coming in "Whidbey", I believe).

I've been looking for a WIN32 multithreaded server sample for quite some time now. I've found a few on Codeproject and some on Codeguru, but none of them explained how to get past my biggest problem. They all seem to start some sort of acceptor that fires off a client thread for handling the client, but then it just waits for the client to disconnect, or for an error to occur. The thing that is never explained, and which i can't find a solution for is what if we need to boot a client from the server?? I mean, how can we let a client thread know that it has to stop looping and handling the client in a normal way? (I'm talking strictly win32 code, blocking mode)
I've thought about doing a select in the client thread so it could occasionally check for a flag wether as to exit or not. But this turned out to be rather messy and i'm sure there is some better way, that also would influence the performance a little less.

Do you mean, you don't know how the client thread know when to exit?
You're calling recv() in a loop, parsing the commands, if there is an exit command, then exit thread (and clean up, send exit response or what ever...) and if recv() returns 0 it means the other side closed the connection.

No no no, thats exactly what i don't mean. I mean disconnecting the client from the server, from the server side. Like booting, kicking a client, whatever u want to call it. Manually that is.

I see, but that depends on your code. You can just call closesocket() on the socket and then it will close. Save all your clients in a std::vector or std::list (whatever) and iterate through it to find the specific client and call closesocket().
